thanks to all that have replied.
I guess at the end of it all scott's last post on this thread really does sum it up.
I suppose the debate will rage on however but it's a question I really needed an answer to ,due to the fact I will be targeting the flattie over the next 2 weeks (nugget's club comp you see) and I really was hopeing that if I was lucky enough to nab a couple then I would of been able to tell if they were he's or she's with the later going back of course.
once again thanks to all, I got the idea of it now.
